Non-linear systems Memes

The eternal scream-off between a student and non-linear systems is the academic equivalent of trying to reason with a cat. Linear systems behave predictably—put in X, get Y. But non-linear systems? They're the chaotic roommate who eats your food and replaces it with interpretive dance. One minute your differential equation is solvable, the next it's having an existential crisis. Students worldwide unite in that primal scream when realizing their homework has gone from "solve for x" to "predict the butterfly effect while standing on one foot." The mathematical equivalent of asking "why can't you just be normal?" to which chaos theory responds with unholy screaming.
